8 Claims.

This invention relates to an improvement in sash windows and more particularly to those which may be manipulated to facilitate cleaning orto change or control ventilation of a room.

The preferred embodiment of the invention discloses a unitary structure, insertable as such,

into a window opening and which consists essentially of a building frame, guide frame and one or more sash windows.

It is recognized that windows of the sash type constructed from wood do not lend themselves as readily to improvement necessitated by the continuous advance in building design. The more recent trend, therefore, has been to develop sash windows in metal which would meet all the requirements of the wood window and in addition have certain advantages thereover.

The principal objection to windows constructed from metal lies in their cost of manufacture and installation. It has become increasingly evident that the cost of metal windows must be greatly reduced to compete with the reasonable price of wooden windows of this type. The present invention represents a development and refinement of metal window parts for the purpose of providing an inexpensive metal window which may be easily assembled or disassembled and this therefore constitutes the principal object of the invention.

Another object of the invention lies in the provision of a window structure of this class comprised of a stationary or building frame, a removable guide frame, and one or more sash windows remo'vably mounted in the guide frame.

A further object of the invention lies in the provision of a window structure of this class in which a sash and guide frame maybe simultaneously swung inwardly for the purpose of permitting cleaning the exterior surface of the sash. A still further object of the invention lies in the provision of a window structure of this class in which a weather seal is provided between each pair of relatively movable elements, the parts for this purpose being definitely associated with each of the elements.

Another and further object of the invention lies in the provision of a window structure of this class which, by reason of the simplicity of design of the component parts thereof, makes possible the manufacture and assembly of a comparatively inexpensive metal window.

Other and further objects of the invention will be more clearly understood from a consideration 55 of the following specification which is taken in conjunction with the accompanying drawings and in which,

Figure l is a vertical sectional view of one modification of this invention showing the guide frame swung inwardly of the fixed or building 5 frame;

Figure 2 is an enlarged vertical sectional view showing upper and lower sashes mounted in the guide frame and the guide frame located in the building frame; 10

Figure 3 is an enlarged fragmentary vertical sectional view showing details of structure which permit swinging the guide frame and sashes inwardly of the building frame;

Figure 4 is an enlarged horizontal sectional 15 view taken substantially on the line 4-4 of Figure 2;

Figure 5 is a partially exploded perspective view of the elements which comprise one of the sashes;

Figure 6 is a disassembled View of a pair of 20 complemental elements which make up one rail of a sash;

Figure '7 shows the complemental elements assembled to form a sash rail, being taken substantially on the line ll of Figure 5; and 5 Figure 8 is a vertical sectional view of a part of the building frame showing weather strip portions mounted therein.

Referring to the drawings, one modification of the invention is shown. This structure is adapt- 30 able for mounting in assembled form as a unit into a suitably proportioned building wall opening. For the purpose of a clearer understanding of the invention, the structure is considered as being comprised of a fixed or building frame, guide frame, and sash.

The building frame, generally indicated by the reference numeral It, is of any desired generally channel shape in cross section, the present disclosure providing a base wall I l, inner side wall i2, and outer side wall I3. (Fig. 4). The inner wall I 2 terminates in a flange I isubstantially parallel with the wall H. The outer wall may be, as shown in the drawings, formed with any suitable trim Hi, this trim terminating in turn in an inwardly directed flange ll substantially parallel to the wall I I. Secured to the inner face of the flange l8 adjacent flange H, is a full length strip 20 which together with flange 11 forms a full length V-shaped pocket 2 I, the purpose of which is hereinafter more fully described. The compartment 23, formed by the walls of the building frame it, serves to house sash cables and weights, an angle strip 24 being welded or otherwise joined to the wall I l to space the weights of 7'0 r frame when it is swung inwardly on the pads 35.

i As. heretofore mentioned, the guide'frame is U- and top wall 4|. frame are of identical contour, only one will be described in detail. Reference is now had par the upper and lower sashes. The head portion 26 of the frame 10, similar in contour to the structure above described, may be provided with a knob 21 supported on a shaft 28. The inner end of this shaft is fitted with a latch member 29 which may be rotated by the knob 2'! to engage and retain the guide frame in position within the build-' ing frame. Although the shaft 28 and knob '21 are shown mounted in a removable trim memher 39, the trim can form part of the building frame and the particular method of mounting this latch constitutes no part of the invention. i Thesill 32 of the fixed frame it is of conventional design with the exception that a horizontal rail portion 33 thereof on which the guide frame rests is formed with suitable indentures 34 in which are located fiber or other pads35.

The guide frame 38 considered as a whole is U-shaped, being comprised of side walls 39'and Inasmuch as the sides of the ticularly to Figure 8 wherein the wall 39 is shown tobe divided into two adjacent vertical portions separated by a rib 43. This rib may be formed from a separate element or, as disclosed, be made integral with the adjacent portions of the wall 39. Theinner vertical edge of the wall 39 terminates in a return bent flange 44 which provides a full length pocket or recess 45. From 'the'flange 44 a finished portion is provided by flanges 43, 4?

and 48. The flange 48 terminates in a return flange 49 which, when the guide frame is mounted in the building frame, overlaps flange M of said frame. The outer vertical edge of the wall 39 is formed' with a return bent flange 5| which provides a recess or pocket 52. From the flange 5| the wall is continued in flanges 53 and 54, the

latter being adapted to. fit into the V-shaped' pocketZl formed in the building frame I0. Figure 4 clearly discloses the manner in which the 1 vertical wall 39 of the guide frame functions to produce a weather tight seal with the correspond- .53 serves with" the rib 43 and wall 39 to provide a guideway for the upper sash, whereas flange 46,

wall 39 and rib 43 provide'a guideway for the lower sash. Midway of each of the walls 39. and 40 are openings 6| through which the sash weight 7 cables project to be joined to the sashes.

Flanges 46,141, 48 and 49 of the walls 39 and 49 are cut away at their lower ends to provide shoulders 63' (see Figures 2 and 3), which rest upon pads 35 in the sill 32. A'stop plate 64 is secured in any suitable manner, as by welding, to each of the walls'39 and 40 a short distance upwardly off their lower edges. These plates project utwardly of the walls to which they are joined a s'uflicient distancefor'their engagement with the and 4 0 are somewhat V flexible.

' wall J2 of the building frame l9 and serve to define the limit :of inward movement of the guide shaped, and, being open atthe bottom,"walls 39 V Consequently whenit is desired to entirely remove the guide Similarly a metal strip 53 frame from the building frame the lower ends of Walls 39 and 40 are pressed inwardly toward each other to disengage the stop plates 54 from the walls l2 of the building frame.

The present invention includes provision for upper and lower sashes which are generally indicated by the numerals B6 and 61. With the exception of a weather strip joined to the lower edge of the lower sash 61, these sashes are identi-' cal and therefore only sash 61' will be described in detail. Referring particularly to Figures 5, 6, and 7, it will be noted that the sash 61 is comprised of two rectangular elements 68 and 69.

Theelement 56 is formed with an inner wall 19 which terminates along one vertical edge in a right angle flange H and along the other edge in a trim portion 12 which provides a shoulder l3 against which a glass panel may be positioned.

' From the shoulder 13 a flange 14 continues to form a seat for the edge of the glass panel and this flange in 'turn terminates in a right angle flange l5 which is parallel to the inner wall F0. The other element 69 is provided with an outer wall 71 which terminates along one vertical edge in a right angle flange 18, corresponding to flange ii of the other element. The other vertical edge of the wall 11 terminates in a further trim portion 39 which provides a further glass panel retaining shoulder 8|. From the shoulder 8| flanges 82, 83 and 84 are continued to form a recess 85 into which, when the elements 68 and 39 are assembled, flange l5of the element 68 projects. When these elements are assembled, a portion of the flange 14 lies against the shoulder formed by flanges 82. A plurality of screws 8? are mounted in suitablethreaded openings in the flange 84. These screws when turned down bear against flange 14 at an angle governed by the angularity of flange 84 for the purpose of drawing the two elements into pressure abutment with each other. Rubber or other suitable padding 88 encloses the edges of the glass panel 89 and is engaged, when the elements are assembled, by flanges l3, l4 and 8|. 7

V The sash frame thus far described presents a member havingsuitably finished inner and outer faces and 'a glass panel. The sides, top and bottom of the sash frame, however, present outwardly opening channels. The top of the sash, being exposed to view, is closed by a plate 9| which is provided with return bent flanges 92 along the under face thereof. These flanges form restricted mouth recesses 93 into which flanges H and 18 of the sash frame project.

The springiness of flanges 92 is suflicient to pre-.

vent rattling or accidental dislodgement of this plate. As shown in Figure 2 0f the drawings, the plate til may be provided with a downwardly overhanging portion 95 which forms a sash width shoulder engageable' with a corresponding shoulder on'the bottom plate 96 of the upper sash to provide a weather tight seal at the'hieeting edges of the. two sashes. While the portions 95 and 96 are shown'to be rectangular, it is contemplated that they be formed with interfltting of the lower sash is closed by a flexible plate 98 which is disposed with an angularity corresponding with that of'the sill 32. The edges of this plate are provided with return bent flanges 99 ing flanges l! and 18 of the sash frame. The sides of the sash are closed by metal strips ml. These strips have flanges I02 which are flanges to effect-a better seal thanwith two con- ,tacting portions as disclosed. The bottom edge which form restricted mouth recesses for receiv- V spaced slightly from the adjacent flanges 1| and 18 of the sash frame. The plate projects inwardly of the sash frame having a V-shaped central portion I03 which gives additional flexibility to an already somewhat flexible metal strip. Flanges I02 are adapted to fit into recesses 51 of the plate 55 which, as above set forth, is mounted in the guide frame 38. Interfitting of these elements insures a weather tight seal. Furthermore, since plates 55 and 58 of the guide frame and plates [ill of the sash are of brass or other suitable alloy, excellent bearing contact between the sash and guide frame is had. A slight amount of lubricant between these relatively movable plates is suificient to assure free reciprocation of the sash over a long period of time.

Mounted in the building frame l adjacent the top wall 26 and in any suitable manner, are pairs of rollers I05. The rollers may be of the swivel type or fixed as disclosed in the drawings. If fixed, they will be mounted at an angle to permit unhampered travel of sash cables I06 thereover when the guide frame and sash are swing inwardly of the fixed frame as shown in Figure 2 of the drawings. Each cable has a suitable weight (not shown) secured to one end thereof. The other end of the cable projects through one of the openings 6| in the guide frame and is engaged with a V-shaped bracket it! which is permanently secured to the bottom plate 88 of the lower sash 61 or at the bottom plate 98 of the upper sash 66. The brackets I01 are sufficiently close to the ends of plates 98 and 96 so that the cables I06, when the openings H38 in side plates IDI register with guide frame openings 6|, may be projected into the sashes and engaged with the brackets. Before removing the guide frame entirely from the building frame, the sash cables I06 must be disengaged from the brackets in a manner the reverse of that described.

Although applicant has shown and described only one specific means for fastening two rectangular elements together to form the rails ofa sash, and only one disclosure of suitable weather stripping means for the sash, it will be apparent to those skilled in the art that modifications or adaptations of this structure may be made and are contemplated in so far as they may be within the scope of the hereunto annexed claims.
